Abstract
The disclosure is directed to a cutting tool assembly used for creating grooves in a microreplication tool. The cutting tool assembly includes a mounting structure and multiple diamonds aligned in the mounting structure to a tolerance of less than 10 microns. For example, first and second tool shanks having first and second diamond tips can be positioned in the mounting structure such that a cutting location of the first diamond tip is identical to a cutting location of the second diamond tip. However, the second diamond tip may be a defined distance further away from the mounting structure than the first diamond tip, or the second diamond tip may have a different shape than the first diamond tip. In this manner, the first diamond tip may cut a groove into a work piece and the second diamond tip may cut a sub-feature into the groove to create a multi-featured groove.
